Answer 2

Answer:

In order to determine the line of symmetry, it would help to put this standard form parabola into vertex form, which is

,

where x = h is the equation of the line of symmetry.

To get this into vertex form we will complete the square. The first couple of steps I will combine into 1. We will set the quadratic equal to zero, then move the constant over to the other side:

The next rule is that the leading coefficient HAS to be a positive 1. Ours is a positive 88, so we have to factor it out:
